ART has shifted the spectrum of HIV-related mortality in the developed world. – <50% of deaths in ART-treated patients are AIDS- related. (ART-CC, Clin Infect Dis 2010, 50:1387) Socially-disadvantaged patients die more often, and of AIDS. New York AIDS registry: (Sackoff JE, Ann Int Med 2006,145:397) – 74% of deaths AIDS-related – Mortality 1.6 times higher in IDU Is excess, AIDS-related mortality seen in such patients who have linked to care? – Is this story changing over time?

 To characterize mortality among HIV-infected patients eligible for ART and linked to care at an urban public hospital ◦ Has mortality decreased in the last decade? ◦ Focus on 5 disadvantaged sub-populations:  Injection drug use  Alcohol abuse  Mental health diagnosis  Non-white race  Female/transgender

Design: Cohort study Setting: Urban safety-net HIV clinic San Francisco, California, USA Patients among the poorest in the city Patients: All patients linked to care & eligible for ART – ≥2 primary care visits – CD4 nadir ≤350 cells/mm 3 – Jan through Aug – N = 1651

Measurements: At study entry: CD4/VL, HIV risk factors, prior ART Mortality: chart review & death index Analyses: Cox proportional hazards with delayed entries Primary comparison: mortality in vs /1/05: midpoint of study period & decade Secondary analyses: Disadvantaged subpopulations Causes of death, viral suppression

Viral Suppression at Any Point Deaths (n = 172) Survivors (n = 1479)

Mortality was high & did not improve over time. 10% over 4 years (2.6% per person-year) in % (2.7% per person-year) in Increased among IDU and other disadvantaged groups HIV-related mortality still dominates. Liver, heart, renal + non-AIDS cancer: <10% of deaths Most patients who died never suppressed their viral loads.

 In developed countries, wide disparities in mortality still exist among PLWHA. ◦ High mortality in socially-disadvantaged populations despite linkage to highest-quality care ◦ Parallel research needed on “old” & “new” HIV epidemics  Intensive, multi-dimensional approach needed  Future research directions: ◦ Comparing mortality among at-risk HIV-infected patients with non-infected peers ◦ Impact of linkage vs. maintenance of care
